摘要：
Poly alpha-1,3-glucan ether compounds are disclosed herein comprising positively charged organic groups. The degree of substitution of the ether compounds is about 0.05 to about 3.0. Also disclosed are methods of producing poly alpha-1,3-glucan ether compounds having positively charged organic groups, as well as methods of using these ether compounds for increasing the viscosity of a aqueous compositions. Hydrocolloids and aqueous solutions comprising the ether compounds are also disclosed.
